BUSINESS lNSTRUCTION AND PRACTICE BOOK.

SPECIFICATION forming part of Letters Patent No. 514,619, dated February13, 1894.

Application filed June 17,1893.

To on whom it may concern.-

Be it known that I, CHARLES L. ELLIs, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented a new and useful Business Instruction andPractice Book, of which the following is a specification.

My invention relates to means for instructing in bookkeeping and otherbusiness operations, and it consists, essentially, in a book or tabletinvolving certain novel features of construction and arrangement whichwill be fullydescribed hereinafter in connection with the accompanyingdrawings, and specifically pointed out in the claims.

In the drawings: Figure 1 is a perspective view of a book or tabletembodying my invention. Fig. 2 is a transverse sectional view of thesame. Fig. 3 is a perspective view, showing the book or tablet open.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawlngs.

l designates the back of the book or tablet, which is, preferably, ofheavy cardboard or other stifi material, and 2, 2, represent oppositeretaining strips or flanges, which are disposed parallel with the planeof the back and adjacent to the side edges thereof respectively. Theseretaining strips or flanges are preferably connected to the back bymeans of the flexible webs or sheaths 3. The flexible web or sheath atone edge of the book or tablet, which for convenience I shall term therear edge, is extended to form a flap 4, to which is fixed one edge ofthe foldable cover 5. This cover is fixed to the inner or under surfaceof the flap 4, and its width is equal to the interval between the inneror facing edges of the retaining strips or flanges 2, whereby when thebook or tablet is closed the cover lies between said strips with itsupper surface flush with their upper surfaces.

The leaves 6 are arranged at their side edges between the upper surfaceof the back and the under surfaces of the retaining strips or flanges,and are securely fastened in such positions by means of the clips 7,which extend therethrough. These leaves are printed upon one side onlyand they are arranged with their printed surfaces down or toward theback, whereby when the book or tablet is Serial No. 477,971. (No modeLlopened only the blank rear surface of the first leaf is visible. Thefaces of the leaves are .printed or otherwise provided with forms, suchas are employed in the various business transactions of the particularbranch of work to which the instruction belongs, such forms beingarranged in the book progressively, so that each successive leaf, whenexposed, advances a step in the instruction.

The leaves are provided adjacent to their side edges and parallel withthe inner or facing edges of the retaining strips or flanges with rowsof perforations 8 and 9, and the various forms which are printed uponthe leaves are separated from each other by intermediate tra'nsverselines of perforations 10.

The leaves are designed to be detached at their outer edges by tearingthe same upon the line of perforations 8, in order to enable the leaf tobe folded upon the inner surface of the cover to expose its printedsurface. The cover new forms awriting surface to enable the student tofill out the various blanks thereon, as indicated by the accompanyingnotes of instruction. After properly fillinga blank or form it should bedetached from the book or tablet by tearing upon the line ofperforations 9. After the various forms have been filled, and theinstructions upon the exposed page have been followed with regard to thedisposition of the various slips, the succeeding page may be detached atits outer edge, as above described. In this way only one page of theinstruction book is exposed at a time, and the teacher is enabled tocontrol the quantity of work of his pupil and prevent him from inquiringinto and becoming confused by advanced steps before the rudiments of thesubject have received the proper attention. After the removal of all ofthe leaves contained in the book or tablet a new set may be secured inthe manner indicated in the foregoing description.

Having described my invention, what I claim is- 1. A book or tablethaving a back 1, retaining strips'orfianges 2 arranged parallel with andoverlapping the opposite side edges of the back, leaves fixedpermanently at their edges between the back and the retaining strips andprovided with lines of perforations adjacent to the inner edges of thestrips, and

a cover loosely connected at one edge to one of the strips and adaptedto fold between the inner edges of the strips to lie flush with theupper surfaces thereof when closed, substantially as specified.

2. A book or tablet having a back 1, side retaining strips 2, parallelwith and overlapping the opposite side edges of the back, a cover 5foldably connected atone edge to one of the said strips and adapted whenclosed to fit between the inner edges of the strips, and leaves printedupon one side only and fixed permanently at their side edges beneath thesaid retaining strips with their printed faces toward the back andperforated to enable I 5 them to be released at one edge and folded uponthe inner surface of the open cover to expose their printed surfaces,substantially as specified.

In testimony that I claim the foregoing as 20 my own I have heretoaffixed my signature in the presence of two witnesses.

CHARLES L. ELLIS.
